Summary
Felix Leupold is a Senior Software Engineer based in Berlin with 11 years of experience specializing in TypeScript and React-driven frontends. He has led frontend teams and shipped production-grade UX at organisations ranging from startups to global firms, including FlixBus, DB Systel and FGS Global, and has worked extensively with GraphQL, Apollo, PWAs and React Native. As a long-time freelance senior frontend developer he pairs hands-on implementation with product-focused design sensibilities rooted in his Interface Design studies. Colleagues rely on him for modern architecture choices—Hooks, TypeScript, CSS modules—and for bridging design and engineering into accessible, maintainable UIs. He brings a practical mix of agency, in-house and consulting experience that helps teams move quickly without sacrificing code quality. An uncommon strength is his sustained independent practice alongside senior roles, which sharpens his ability to deliver polished, user-centric frontends under varied constraints.
